He randomly chose 1 of the DVD players to test. Suppose the defective player is one of the three that Mr. Slayer tested. What is the probability that the last one tested was the defective one?Answer by Theo(3504)   (Show Source): You can put this solution on YOUR website!He bought 5. He tested 3. what is the probability that the defective player is the last one tested? The probability of a player being defective is 1/5. He picks one out at random. the probability it is not defective is 4/5. He picks another one out at random. the probability it is not defective is 4/5. He picks another one out at random. the probability it is defective is 1/5. the probability that he picks the first 2 that are not defective and the third one that is defective would be 4/5 * 4/5 * 1/5 = 16/125
